It currently returns 403 only as a side effect of `fof.xml`'s wildcard-deny resolving under the singularised ACL key `app`, which has no explicit allow rule — not because of any deliberate check. Behind that path, `applocalizationdata::getInstallerTool()` used a caller-influenced table name with no allow-list, both to select a `#__j2store_*` table for truncation and to build a path to SQL files it then executes — a path-traversal-capable file read/execute.","cwe":["CWE-862"],"affected":[{"package":null,"product":"J2Store extension for Joomla","vendor":"j2commerce.com","ecosystem":null,"cpe":null,"version_start":"1.0.0","version_end":"3.3.21","version_end_inclusive":true,"fixed_version":null,"type":null,"source":"nvd"},{"package":null,"product":"J2Store extension for Joomla","vendor":"j2commerce.com","ecosystem":null,"cpe":null,"version_start":"4.0.0","version_end":"4.0.21","version_end_inclusive":true,"fixed_version":null,"type":null,"source":"nvd"},{"package":null,"product":"J2Store extension for Joomla","vendor":"j2commerce.com","ecosystem":null,"cpe":null,"version_start":"4.1.0","version_end":"4.1.6","version_end_inclusive":true,"fixed_version":null,"type":null,"source":"nvd"}],"references":[{"url":"https://www.j2commerce.com/","title":null,"source":"nvd"}],"source_records":[{"source":"nvd","external_id":"CVE-2026-78069","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-78069","severity":"CRITICAL","cvss_score":9.5,"cvss_vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","cvss_version":"4.0","first_seen_at":"2026-09-26T09:34:34.595707Z","last_seen_at":"2026-09-26T09:34:34.595707Z"}],"history":[{"at":"2026-09-26T09:34:34.595707Z","event":"created","source":"nvd","detail":"Détectée via nvd"}]}}
